Question 62

A particle $P\,$ is projected from a point on horizontal ground with velocity $k(3i+4j)k(3\mathbf{i} + 4\mathbf{j})$ m s $^{-1}$ , where $k\,$ is a positive constant, $i\mathbf{i}$ is horizontal and $j\mathbf{j}$ is vertically upwards.

The greatest height reached by $P\,$ is 24 m above the ground.

Find the exact value of $k$ .

[3]

Find the horizontal distance travelled by $P\,$ before it returns to the ground.
